The male caller identified himself as calling on behalf of a fireman's association on June 29th.  As soon as I said I would not be able to donate he hung up.  Also got a call from 707-070-4909 (caller ID also "California") on June 18th.  The person asked my wife if I was home.  She said no and he hung up.

Got another call from this number this morning.  Today, "Kevin" told me I donated money to something dealing with breast cancer last year and that they were going to hope for the same donation this year.  I told him "no thanks" and the call was immediately dropped.  Same number has called me twice now with different groups wanting money.  Sounds pretty fishy.
